Tham Pha Nang Khoi
Another interesting cave is Tham Pha Nang Khoi which is about 40 kilometres north of town on Highway No. 101 at Km. 59 within Rong Kwang district. A 50 metre-long rail leads to the cave mouth. Along the winding tunnels are strangely-shaped stalactites and stalagmites. At the end of the cave is a stalagmite shaped like a woman holding a small child. In front of the Nang Koi (waiting woman) stone is a heart-shaped stalactite. They are the source of the legend of the love of a woman who waited for her lover until she turned into stone. Amid cool forested area is the Huai Rong Waterfall. It can be reached by taking Highway No. 101 (Phrae-Rong Kwang) and go on for 60 kilometres northward. Turn left at Km. 78 and proceed on for a further 4 kilometres.
